[0043] Figure 1 Schematic diagram of a brush roller module according to an embodiment of the present application;

[0044] As Figure 1 shown, an embodiment of the present application provides a brush roller module 100, which includes:

[0045] The roller body 110 takes away the dirt on the surface to be cleaned by rotating. One end of the roller body 110 is provided with a bracket 170. The bracket 170 is connected to the roller body 110 through a connecting shaft 171, and the roller body 110 rotates relative to the bracket.

[0046] The air generating part is configured to form at least partial air volume between the bracket 170 and the roller body 110.

[0047] Among them, the rotary brush module 100 includes a roller body 110, and the dirt on the surface to be cleaned can be taken away by the rotation of the roller body 110. Usually, the bracket 170 is fixed. After the roller body 110 is connected to the bracket 170 through the connecting shaft 171, the roller body 110 rotates while the bracket 170 remains stationary. At this time, strip-shaped garbage, such as hair, will be wound around the connecting shaft 171 between the bracket 170 and the roller body 110. By forming an air volume between the bracket 170 and the roller body 110 through the air generating part, the strip-shaped garbage can be blown away from the position of the connecting shaft 171 between the bracket 170 and the roller body 110, thereby preventing the strip-shaped garbage from being brought into the connecting shaft 171 when the roller body 110 rotates and affecting the subsequent rotation of the roller body 110. That is to say, by setting the air generating part, wind energy can be concentrated at the bracket 170, and the strip-shaped garbage can be blown away from the bracket 170 by the wind energy, preventing the strip-shaped garbage from winding around the connecting shaft 171 of the bracket 170 and affecting the rotation of the roller body 110, ensuring the working reliability and stability of the rotary brush module 100, and being able to extend the service life of the rotary brush module 100.

[0048] Specifically, the bracket 170 is connected to the roller body 110 through the connecting shaft 171 and a bearing. The rotation of the roller body 110 will bring strip-shaped garbage to the connecting shaft 171, resulting in the strip-shaped garbage winding around the connecting shaft 171. The air generating part is configured to form at least partial air volume between the bracket 170 and the roller body 110. That is to say, an air flow is formed near the bracket 170 through the air generating part, and the strip-shaped garbage, such as hair and broken wires, gathered near the bracket 170 is blown away from near the bracket 170 to prevent the strip-shaped garbage from winding around the connecting shaft 171 of the bracket 170 and being unable to be cut, thereby affecting the subsequent rotation of the roller body 110. That is to say, when the strip-shaped garbage cannot wind around the connecting shaft 171 of the bracket 170 or only a small number of strip-shaped garbage winds around the connecting shaft 171 of the bracket 170, the working reliability and stability of the rotary brush module 100 can be ensured. It can be understood that the small number refers to 1 to 5 strip-shaped garbage, or the number of strip-shaped garbage that does not affect the normal rotation of the roller body 110.

[0049] Figure 2 Schematic diagram of the air supply part according to an embodiment of the present application; Figure 3 Schematic diagram of the air supply part according to another embodiment of the present application.

[0050] In a feasible implementation manner, such asFigure 2 and Figure 3 As shown, the air supply part includes the first air generation part 150 and / or the second air generation part 160; among them,

[0051] The first air generation part 150 leads at least part of the external air volume to between the bracket 170 and the roller body 110 through the first pipeline;

[0052] The second air generation part 160 includes an air forming structure, and the air forming structure rotates to form an air volume.

[0053] Among them, the air generation part can only include the first air generation part 150, or the air generation part only includes the second air generation part 160, or the air generation part includes both the first air generation part 150 and the second air generation part 160 in three cases.

[0054] Specifically, when the air generation part only includes the first air generation part 150, the first air generation part 150 includes a first pipeline (not shown), and one end of the first pipeline can be connected to any space that can form an air volume, and the other end of the first pipeline is led to the connecting shaft 171 between the bracket 170 and the roller body 110, that is, the position between the roller body 110 and the bracket 170. By leading the air volume of other spaces to between the bracket 170 and the roller body 110, the strip-shaped garbage near the connecting shaft 171 of the bracket 170 can be blown away. This space that forms the air volume can be to set up a single fan so that the fan forms an air volume in a space, or the dust suction fan of the automatic cleaning device 200 where the brush roller module 100 is located can be used. When setting up a single fan, since there is no need to draw part of the air volume of the dust suction fan, the dust suction air volume of the automatic cleaning device 200 can be ensured not to be affected. When using the dust suction fan, there is no need to change the size of the main body of the automatic cleaning device 200, and the volume and weight of the automatic cleaning device 200 can also be ensured to remain unchanged, and it can be selected according to actual needs. When the air generation part only includes the second air generation part 160, the second air generation part 160 includes an air forming structure, and the power structure makes the air forming structure rotate, so that the second air generation part 160 forms a rotating air flow near the bracket 170, or leads the air flow of the air forming structure to near the bracket 170, thereby preventing the strip-shaped garbage from winding around the connecting shaft 171 of the bracket 170.

[0055] It can be understood that the first air generation part 160 and the second air generation part 160 can be set in the brush roller module 100 at the same time, so as to ensure that enough air volume is sent to the connecting shaft 171 of the bracket 170, and further achieve the purpose that the strip-shaped garbage cannot wind around the bracket 170.

[0056] In a feasible implementation manner, a baffle 120 is provided at one end of the roller body 110, the baffle 120 is located between the roller body 110 and the bracket 170, and the first air generation part 150 and / or the second air generation part 160 form at least part of the air volume between the bracket 170 and the baffle 120.

[0057] It should be noted that a baffle 120 is provided at one end of the roller body 110. The baffle 120 is located between the roller body 110 and the bracket 170, and the baffle 120 is integrally formed with, welded to, or detachably connected to the roller body 110. Usually, the first pipe of the first air supply part 150 passes through the brush housing and the bracket 170 to lead at least part of the air volume between the bracket 170 and the baffle 120, so that an air volume is formed between the bracket 170 and the baffle 120. The second air supply part 160 directly forms an air volume between the bracket 170 and the baffle 120 through the rotation of the air-forming structure, or the second air supply part 160 forms an air volume through the rotation of the air-forming structure and leads the air volume to the position between the bracket 170 and the baffle 120.

[0058] It can be understood that one end of the roller body 110 is connected to the bracket 170, and the other end of the roller body 110 is suspended. The support of the roller body 110 is realized by one bracket 170. Therefore, an air supply part can be provided at the end of the roller body 110 connected to the bracket 170. That is to say, in the length direction of the roller body 110, as Figure 1 shown, the right side of the roller body 110 is the first end of the roller body 110, the left side of the roller body 110 is the second end of the roller body 110, and the first air supply part 150 and / or the second air supply part 160 are provided at the first end of the roller body 110. That is to say, only the first air supply part 150 is provided at the first end of the roller body 110, or only the second air supply part 160 is provided at the first end of the roller body 110, or both the first air supply part 150 and the second air supply part 160 are provided at the first end of the roller body 110.

[0059] In a feasible implementation manner, the first air supply part 150 includes at least one air supply channel 151 provided on the roller body 110, and the air supply channel 151 penetrates through the baffle 120. One end of the first pipe is connected to the air outlet of the fan, and the other end of the first pipe is located inside the air supply channel 151; and / or a central channel is provided in the center of the roller body 110, the air supply channel is communicated with the central channel, one end of the first pipe is connected to the air outlet of the fan, and after the first pipe passes through the air supply channel, the other end of the first pipe is arranged inside the air supply channel 151.

[0060] Among them, at least one air supply channel 151 is arranged on the outer periphery of the roller body 110, and the air supply channel 151 penetrates through the side wall of the roller body 110 and the baffle 120, so that it is convenient for the first pipeline to lead the air of the fan to the space between the support 170 and the baffle 120, and then form an air flow between the support 170 and the baffle 120, avoiding the strip-shaped garbage from winding around the connecting shaft 171 of the support 170. When the first air supply part 150 includes a plurality of air supply channels 151, the plurality of air supply channels 151 can be evenly arranged on the outer periphery of the roller body 110, or a plurality of air supply channels 151 can be arranged only on a part of the outer periphery of the roller body 110, as long as an air flow can be formed between the support 170 and the baffle 120, and no specific restrictions are imposed on the distance between adjacent two air supply channels 151, the inclination angle, etc.

[0061] It can be understood that when there are a plurality of air supply channels 151, one end of the first pipeline is communicated with the space where the fan is located, and the other end of the first pipeline is provided with a plurality of air outlets, and the plurality of air outlets are respectively communicated with the plurality of air supply channels 151, so that it can be avoided that the first pipeline is wound when rotating with the roller body 110, ensuring the ventilation function of the first channel, and further ensuring the reliability of the operation of the first air supply part 150.

[0062] It should be noted that the air supply channel 151 on the outer periphery of the roller body 110 can be a groove-shaped channel, and the first pipeline is installed in the groove-shaped channel, and the other end of the first pipeline needs to penetrate through the baffle 120, so that the air volume can be led to the space between the support 170 and the baffle 120. At this time, the groove-shaped channel is the receiving groove of the first pipeline; or the air supply channel 151 on the outer periphery of the roller body 110 can be a closed channel, that is, a first opening is provided on the outer periphery of the roller body 110, and a second opening is provided on the baffle 120, and the first opening and the second opening are communicated to form a closed air supply channel 151, and the first pipeline is arranged in the closed air supply channel 151. At this time, the length of the first pipeline can be effectively shortened, that is, the first pipeline is fixed in the first opening, and the air volume can be led to the space between the support 170 and the baffle 120 through the closed channel.

[0063] Among them, in order to realize the connection between the roller body 110 and the connecting shaft 171 of the support 170, a central channel is provided at the axial center of the roller body 110, and at least part of the connecting shaft 171 is located in the central channel. At this time, the air supply channel 151 can penetrate through the side wall of the roller body 110, so that the air supply channel 151 is communicated with the central channel. One end of the first pipeline is connected to the space where the air outlet of the fan is located, and the other end of the first pipeline is arranged in the air supply channel 151. Since the central channel is a blind hole and the connection between the central channel and the connecting shaft 171 of the support 170 is not completely sealed, at this time, through the air supply channel 151 and the central channel, the air volume of the fan can be led to the position between the support 170 and the baffle 120, avoiding the strip-shaped garbage from winding around the connecting shaft 171 of the support 170.

[0064] In a feasible implementation, the air-forming structure includes:

[0065] Blades 161, at least one blade 161 is disposed on the baffle 120, and at least a part of the blade 161 is located on the baffle 120, and the blade 161 extends towards the bracket 170.

[0066] Meanwhile, the rotary brush module 100 further includes a first motor, the first motor is disposed inside the roller body 110, and the first motor drives the roller body 110, the baffle 120 and the blade 161 to rotate simultaneously.

[0067] Wherein, when the blade 161 is disposed on the baffle 120, it may be that part of the blade 161 is located on the roller body 110, and the blade 161 penetrates through the baffle 120 and extends towards the bracket 170, or all the blades 161 are located on the baffle 120. When part of the blade 161 is located on the roller body 110, the blade 161 may be integrally formed with the roller body 110, or the roller body 110 and the blade 161 may be connected by bayonet connection, welded connection, matching connection of protrusions and grooves or threaded connection; when all the blades 161 are located on the baffle 120, the blade 161 and the baffle 120 may be integrally formed, bayonet-connected, welded-connected or connected by matching connection of protrusions and grooves.

[0068] It should be noted that usually the blade 161 is inclined, and the blade 161 is inclined in the direction of rotation of the roller body 110. In this way, when the first motor (not shown) drives the roller body 110 to rotate, it simultaneously drives the baffle 120 and the blade 161 to rotate, forming a centrifugal fan structure in the space between the baffle 120 and the bracket 170. In this way, the airflow between the baffle 120 and the bracket 170 can prevent strip-shaped garbage from entering the space between the baffle 120 and the bracket 170, that is, it can avoid the strip-shaped garbage from winding around the connecting shaft 171 of the bracket 170.

[0069] It can be understood that the blade 161 extends towards the bracket 170, and the side of the blade 161 away from the baffle 120 is separated from the side of the bracket 170 facing the baffle 120 by a first distance. Through the setting of the first distance, it can be avoided that the blade 161 collides with the bracket 170 when rotating. On the one hand, it can ensure the service life of the bracket 170 and the structural stability, and on the other hand, it can ensure the working reliability of the rotary brush module 100.

[0070] In a feasible real-time manner, when the air-forming structure includes a plurality of blades 161, the height of each blade 161 is different; or at least two blades 161 have the same height;

[0071] Wherein, the height of the blade 161 is the distance between the end of the blade 161 away from the baffle 120 and the baffle 120.

[0072] When the air-forming structure includes multiple vanes 161, the distances between the ends of the vanes 161 away from the baffle 120 and the baffle 120 can be the same or different. That is to say, the first distances can be different, or the first distances can be the same. The first distance can be any value between 1 mm and 3 mm, as long as an air flow is formed in the space between the baffle 120 and the bracket 170. At the same time, the multiple vanes 161 are arranged around the central axis of the roller body 110, and the distances between the multiple vanes 161 are not limited. That is, the multiple vanes 161 can be evenly arranged in a ring on the baffle 120 (roller body 110), or the multiple vanes 161 can be unevenly arranged on the baffle 120 (roller body 110). When the vanes 161 are unevenly arranged, although the air flow does not act evenly in the space between the baffle 120 and the bracket 170, an air flow can still be generated to prevent the strip-shaped garbage from winding around the connecting shaft 171 of the bracket 170.

[0073] In a feasible real-time mode, the roller body 110, the baffle 120, and the bracket 170 are arranged in the roller brush housing, and the roller brush housing is configured on the main housing of the automatic cleaning device;

[0074] The roller brush housing is provided with a first air-forming space, and the air-forming structure is arranged in the first air-forming space. The air-forming structure includes: vanes 161, a second motor, and a second pipe. The second motor drives at least one vane 161 to rotate to form an air volume, and the air volume is led to the space between the bracket 170 and the baffle 120 through the second pipe; or

[0075] The main housing is provided with a second air-forming space, and the air-forming structure is arranged in the second air-forming space. The air-forming structure includes: vanes 161, a third motor, and a third pipe. The third motor drives at least one vane 161 to rotate to form an air volume, and the air volume is led to the space between the bracket 170 and the baffle 120 through the third pipe.

[0076] Specifically, the first air-forming space is enclosed by the enclosing plate and the roller brush housing, and the air-forming structure is arranged in the first air-forming space. At the same time, one end of the second pipe is arranged in the first air-forming space, and the other end of the second pipe is connected to the space between the bracket 170 and the baffle 120 to lead the air formed by the air-forming structure in the first air-forming space to the space between the bracket 170 and the baffle 120. It should be noted that the first air-forming space can be located in the axial direction of the roller body 110, or the first air-forming space can be located in the radial direction of the roller body 110.

[0077] It should be noted that at this time, the air-forming structure should also include a mounting plate. The blade 161 is arranged on the mounting plate, and the mounting plate is located in the first air-forming space. At this time, a power structure needs to be additionally provided. The power structure is a second motor (not shown). The fixed end of the second motor is arranged on the roller brush housing, and the output shaft of the second motor is fixedly connected to the mounting plate. The blade 161 is arranged on the mounting plate. In this way, the rotation of the second motor drives the mounting plate and the blade 161 to rotate, forming an air flow in the first air-forming space. The air flow is led between the bracket 170 and the baffle 120 through the second pipeline, which can prevent hair from staying near the bracket 170. The mounting plate can be circular, square, rectangular, or any other irregular shape, as long as it does not rub against the side wall of the first air-forming space during the rotation of the mounting plate driving the blade 161.

[0078] Among them, when the first air-forming space is in the axial direction of the roller body 110, since the first air-forming space is relatively close to the bracket 170, the length of the second pipeline can be effectively shortened; when the first air-forming space is in the radial direction of the roller body 110, although the length of the second pipeline increases, the area of the roller brush module 100 on the plane to be cleaned can be reduced, that is, the floor area of the automatic cleaning device 200 can be reduced. Through the setting of the air-forming structure, an air volume can be formed between the bracket 170 and the baffle 120. On the one hand, the strip-shaped garbage near the bracket 170 can be blown towards the center of the roller body 110, facilitating the roller body 110 to clean the strip-shaped garbage into the accommodation box. On the other hand, it can also prevent the strip-shaped garbage from winding around the connecting shaft 171 of the bracket 170.

[0079] It can be understood that there is a certain distance between the blade 161 of the air-forming structure and the enclosure of the first air-forming space, that is, the blade and the first air-forming space are in clearance fit. Such a setting can prevent the blade 161 from colliding with the enclosure of the first air-forming space when rotating. On the one hand, it can ensure the service life of the first air-forming space and the structural stability, and on the other hand, it can ensure the working reliability of the roller brush module 100. At the same time, when the air-forming structure includes multiple blades 161, the heights of the multiple blades 161 can be the same or different. The height of the blade 161 refers to the distance between the end of the blade 161 far from the mounting plate and the mounting plate. At the same time, the multiple blades 161 can be evenly arranged in a ring along the output shaft of the second motor, or can be arranged in a non-uniform ring, as long as an air flow can be formed in the first air-forming space, and there are no other restrictions.

[0080] In another embodiment, a second air-making space is enclosed by a shroud and the main body housing. The air-forming structure is disposed within the second air-making space. Meanwhile, one end of a third duct is disposed within the second air-making space, and the other end of the third duct is connected between the bracket 170 and the baffle 120, so as to guide the air formed by the air-forming structure within the second air-making space to the space between the bracket 170 and the baffle 120. It should be noted that the second air-making space may be located in the axial direction of the roller body 110, or may be located in the radial direction of the roller body 110.

[0081] Specifically, at this time, the air-forming structure should further include a support plate. The blade 161 is disposed on the support plate, and the support plate is disposed within the second air-making space. When the support plate is located within the second air-making space, a power structure needs to be additionally provided. The power structure is a third motor (not shown). The fixed end of the third motor is disposed on the main body housing, and the output shaft of the third motor is fixedly connected to the support plate. The blade 161 is disposed on the support plate. Thus, the rotation of the third motor drives the support plate and the blade 161 to rotate, forming an air flow within the second air-making space. The air flow is guided to the space between the bracket 170 and the baffle 120 through the third duct, which can prevent hair from staying near the bracket 170. The support plate can be circular, square, rectangular, or any other irregular shape, as long as it does not rub against the side wall of the second air-making space during the rotation of the support plate driving the blade 161.

[0082] It should be noted that when the second air-making space is located in the axial direction of the roller body 110, since the second air-making space is relatively close to the bracket 170, the length of the third duct can be effectively shortened; when the second air-making space is located in the radial direction of the roller body 110, although the length of the third duct increases, the area of the brush roller module 100 on the surface to be cleaned can be reduced, that is, the floor area of the automatic cleaning device 200 can be reduced. By arranging the air-forming structure to form an air volume between the bracket 170 and the baffle 12, on the one hand, the strip-shaped garbage near the bracket 170 can be blown towards the center of the roller body 110, facilitating the roller body 110 to clean the strip-shaped garbage into the receiving box, and on the other hand, the strip-shaped garbage can be prevented from winding around the connecting shaft 171 of the bracket 170.

[0083] It can be understood that there is a certain distance between the blades 161 of the air-forming structure and the enclosure of the second air-braking space, that is, the blades and the first air-braking space are in clearance fit. Such a setting can prevent the blades 161 from colliding with the enclosure of the second air-braking space when rotating. On the one hand, it can ensure the service life of the second air-braking space and the structural stability, and on the other hand, it can ensure the working reliability of the roller brush module 100. At the same time, when the air-forming structure includes multiple blades 161, the heights of the multiple blades 161 can be the same or different. The height of the blade 161 refers to the distance between the end of the blade 161 far from the support plate and the support plate. At the same time, the multiple blades 161 can be evenly arranged in a ring along the output shaft of the third motor, or can be arranged in a non-uniform ring, as long as it can form an air flow in the second air-braking space, without other restrictions.

[0084] It should be noted that the above three setting forms of the air-forming structure include at least one, or can include two, or can include three setting forms of the air-forming structure. When including two setting forms of the air-forming structure, that is, setting the air-forming structure on the baffle 120 and in the first air-braking space at the same time, or setting the air-forming structure on the baffle 120 and in the second air-braking space at the same time, or setting the air-forming structure in the first air-braking space and the second air-braking space at the same time. The setting methods of multiple air-forming structures can better form an air flow near the bracket 170. However, if the air flow is too large, it will also affect the cleaning of the dirt on the surface to be cleaned by the roller body 110. Therefore, select the parameters of different power structures and different setting methods of the air-forming structure according to actual needs.

[0085] It can be understood that fans can also be set in the first air-braking space and the second air-braking space to form an air volume in the first air-braking space and the second air-braking space. The air volume in the first air-braking space is led to between the bracket 170 and the baffle 120 through the second pipeline; similarly, the air volume in the second air-braking space is led to between the bracket 170 and the baffle 120 through the third pipeline, which can also achieve the purpose of avoiding the winding of strip-shaped garbage on the connecting shaft of the bracket 170 in this application, and also belongs to the protection scope of this application.

[0086] Figure 4 Schematic diagram of the air supply structure according to an embodiment of the present application; Figure 5 Schematic diagram of the air supply structure according to another embodiment of the present application.

[0087] In a feasible implementation manner, as Figure 4 and Figure 5 shown, the projection of the blade 161 on the plane perpendicular to the rotation axis of the blade 161 is rectangular, arc-shaped, triangular, polygonal, or other irregular shapes.

[0088] It should be noted that the projection of the blade 161 on the plane perpendicular to the blade rotation axis can be rectangular, arc-shaped, triangular, polygonal, or other irregular shapes. That is to say, there is no restriction on the shape of the blade 161.

[0089] It can be understood that when the wind generating structure includes multiple blades 161, the multiple blades 161 can be of the same shape or different shapes. That is, the multiple blades 161 can be rectangular, arc-shaped, triangular, polygonal, or other irregular shapes at the same time, or the multiple blades 161 can be rectangular, arc-shaped, triangular, polygonal, or other irregular shapes respectively.

[0090] Figure 6 It is a schematic diagram of a wind generating structure according to another embodiment of the present application.

[0091] As Figure 6 shown, in the present application, one end of the blade 161 close to the rotation center is the first end, and the end of the blade 161 far from the rotation center is the second end. The distance between the first end and the second end can be the same or different. That is to say, when the distance between the first end and the second end is set as the length of the blade 161, the lengths of the blades 161 can be the same or different, and the blades 161 with different lengths can be arranged at intervals, or the blades 161 with the same length can be arranged adjacent to each other, as long as the blades 161 can generate air volume after rotation, and there is no restriction on the length of the blade 161.

[0092] In this embodiment, the blade 161 can be set to any integer.

[0093] In a feasible implementation manner, the number of the blades 161 does not exceed 30. Too many blades 161 will increase the burden on the power structure and affect the service life of the power structure. At the same time, too many blades 161 will also bring relatively large noise and affect the user experience. Therefore, the blade 161 can be selected as any integer not exceeding 30.

[0094] In a feasible implementation manner, the roller brush module 100 further includes a cleaning part, and the cleaning part is arranged on the outer periphery of the roller body 110, and the cleaning part 110 is used to pick up the dirt on the ground to be cleaned.

[0095] That is to say, from the end of the blade 161 close to the rotation center to the end far from the rotation center, the height can be changed. That is, the height of the first section is the first height, the height of the second section is the second height, and the height of the Nth section is the Nth height, and the multiple heights are connected in a transitional manner. It can be seen that such a setting form of the blade 161 is also within the protection scope of the present application, as long as it can ensure that a certain air volume is generated after the rotation structure rotates to drive the blade to rotate.

[0096] In a feasible implementation manner, the roller brush module 100 further includes a cleaning part, and the cleaning part is arranged on the outer periphery of the roller body 110, and the cleaning part 110 is used to pick up the dirt on the ground to be cleaned.

[0097] Among them, a cleaning part is arranged on the outer periphery of the roller body 110. The cleaning part protrudes from the outer peripheral surface of the roller body 110, enabling the cleaning part to contact the surface to be cleaned. Furthermore, it is convenient for the cleaning part to pick up the dirt on the surface to be cleaned, achieving the purpose of the rotary brush module 100 cleaning the surface to be cleaned.

[0098] In a feasible implementation manner, the cleaning part includes:

[0099] The first cleaning member 130, and a plurality of the first cleaning members 130 are spirally arranged on the outer periphery of the roller body 110;

[0100] The second cleaning member 140, and a plurality of the second cleaning members 140 are spirally arranged on the outer periphery of the roller body 110. The second cleaning members 140 are arranged at intervals from the first cleaning members 130.

[0101] It should be noted that the first cleaning member 130 is a rubber strip, and the second cleaning member 140 is a brush. During the rotation of the first cleaning member 130 and the second cleaning member 140, the second cleaning member 140 can be tilted towards the first cleaning member 130, and the first cleaning member 130 plays a supporting role for the second cleaning member 140. On the one hand, it avoids the overall tilting of the brush bristles from affecting the cleaning effect of the rotary brush module 100. On the other hand, through the combined use of the rubber strip and the brush bristles, the cleaning efficiency can be improved. For example, the rubber strip is used to clean particulate garbage, and the brush bristles are used to clean dust and strip-shaped garbage. At the same time, through the combined use of the first cleaning member 130 and the second cleaning member 140, the length of the strip-shaped garbage wound around the brush bristles can be extended. That is to say, the first cleaning member 130 has a certain supporting effect on the strip-shaped garbage. Such a setting is more convenient for cleaning the strip-shaped garbage on the brush bristles. On the one hand, it can improve the cleaning efficiency of the brush bristles, and on the other hand, it can also extend the cleaning time of the brush bristles, improving the user experience.

[0102] Among them, the first cleaning member 130 and the second cleaning member 140 are spirally arranged on the outer periphery of the roller body 110, which can increase the contact area between the cleaning part and the surface to be cleaned, improving the cleaning effect and cleaning efficiency of the cleaning part. It can be understood that the spiral angles of the first cleaning member 130 and the second cleaning member 140 are the same, that is, the helix angles are the same. On the one hand, it can ensure the cleaning effect of the cleaning part, and on the other hand, it can also improve the appearance effect of the rotary brush module 100.

[0103] It can be understood that the first cleaning member 130 and the roller body 110 can be connected by insertion. For example, a groove having the same shape as the first cleaning member 130 is provided on the roller body 110, and a protruding portion is provided on the first cleaning member 130. The first cleaning member 130 is fixedly connected to the roller body 110 through the cooperation between the protruding portion and the groove. The connection can also be achieved by welding or adhesive bonding. Similarly, the second cleaning member 140 can also be connected to the roller body 110 by insertion, welding or adhesive bonding.

[0104] In a feasible implementation manner, the first cleaning member 130 includes a first end and a second end. The first end of the first cleaning member 130 is disposed on the roller body 110, and the second end of the first cleaning member 130 is disposed away from the roller body 110. The second cleaning member 140 includes a first end and a second end. The first end of the second cleaning member 140 is disposed on the roller body 110, and the second end of the second cleaning member 140 is disposed away from the roller body 110. The distance between the first end of the first cleaning member 130 and the first end of the second cleaning member 140 is greater than the distance between the second end of the first cleaning member 130 and the second end of the second cleaning member 140.

[0105] Among them, the distance between the first end of the first cleaning member 130 and the first end of the second cleaning member 140 is greater than the distance between the second end of the first cleaning member 130 and the second end of the second cleaning member 140. That is to say, the end of the second cleaning member 140 away from the central axis of the roller body 110 is closer to the end of the first cleaning member 130 away from the central axis of the roller body 110. With such a setting, during the rotation of the rotary brush module 100, the second end of the second cleaning member 140 can be closer to the second end of the first cleaning member 130, that is, the gap between the first cleaning member 130 and the second cleaning member 140 becomes smaller, which can prevent strip-shaped garbage from winding around the brush, reduce the risk of strip-shaped garbage winding around the cleaning part, and further improve the cleaning effect of the rotary brush module 100.
